I think you'd be fine with a HD4850 or HD4870 even. That's a pretty low resolution and I think the HD4870X2 is geared more towards higher resolution.

It would still probably be faster though but it's up to you if its worth the extra money. Also if your using the rig in your sig, I think you're going to be CPU bound so you might consider upgrading your CPU.

Well at that res a better cpu would be better BUT you do have it overclocked to 3.36 So you should be fine. If you want to future proff as much as possible but for a budget get a 4870 or a 4870X2 and a Q6600. Mind you Cross Fire and SLI shine at higher res.

what makes the q6600 better , I mean does 4 cores help current games mutch? such as cod4 & up coming cod world @ war

Well you said you wanted to future prof yourself so a quad is going to be better then a dual core. Especially when DX11 comes out. There are a handful of games that take advantage of a quad core and not to mention when you are running a game and it may only use 2 cores but your operating system is still using up some of those cores so a quad would benefit even for dual core optimized games.
